❓ FAQ
QIs the param tag still in use?
ANo.
<param> passed parameters to plugins inside <object> — mostly Flash — and was marked obsolete as the plugin era ended; modern browsers basically ignore it.QWhat replaced param?
ADifferent scenarios, different replacements: media options became attributes of
<video>/<audio> (autoplay, controls); Flash itself was replaced by HTML5 standards; iframe parameters moved to URL query strings or postMessage.QShould legacy param tags be cleaned up?
AYes — the
<object> Flash scenes they serve cannot run in modern browsers, making the whole block dead code. When migrating, check whether the Flash asset has an HTML5 replacement, then delete the object+param block together.🏷️ Related Tags
